Well, Facebook hasn't chimed in on how exactly will this "Unsend" feature work, but we can expect Messenger users to start taking more screenshots of the conversations once Facebook rolls out the ability to delete messages for all the users. It says examples could include pro-life or pro-choice ads, ads relating to the Second Amendment ads, and ads on issues like public infrastructure. These included limited the retention period for Marks messages in Messenger.

According to the Italian news agency AGI, just over 214,000 Italians could be affected, based on the 57 Facebook users who installed the personality quiz application. Currently, users have no way of deleting sent messages from the recipients' inbox. It's therefore not surprising that Indian users have been are impacted by Facebook's poor privacy norms.

Founder and CEO of SpaceX and Tesla, Elon Musk, who deleted his company pages from Facebook tweeted: "It is not a political statement and I didn't do this because someone dared me to do it".

No notifications were sent to those who had messages deleted, nor was there any disclosure that such a thing was even possible.

The company says it has been removing Mr Zuckerberg's messages from the inboxes of various people for several years and the recipients were not informed before that happened.

In its first official confirmation Facebookadmitted that personal data of up to 87 million of its users was improperly shared with UK-based political consultancy Cambridge Analytica, way higher than the previously estimated 50 million.

"What!? how'd you manage that one?" they asked. "That would be a paid product", Sandberg told NBC News. This will make it much harder for people to run pages using fake accounts, or to grow virally and spread misinformation or divisive content that way.

"But I think we got the balance wrong", she said.

Ms Sandberg gave several interviews as Mr Zuckerberg prepares to testify before Congress next week, where the issue of elections meddling is nearly certain to come up.

Facebook, facing enormous pressure over the scandal, said Friday it had suspended AggregateIQ pending further investigation.

Facebook has said its new terms of service would provide clearer information on how data is collected and shared without giving the social network additional rights. The social media giant later confirmed that it had removed the messages, but claimed that it did so for corporate security reasons.
